A depiction of membrane remodeling in the powerhouse of the oxygen-production (IMAGE)
Caption
The first step of photosynthesis, which involves converting light energy to chemical energy and producing oxygen, takes place in the thylakoid membrane of the chloroplast of a plant cell. The protein VIPP1 plays a critical role in maintaining thylakoid membrane integrity. Left: structure of VIPP1 oligomer, as revealed in this study. Right top: green chloroplasts from an aquatic plant Egeria densa, observed through bright-light microscopy. Right bottom: a protoplast cell of Arabidopsis thaliana seen through a fluorescent microscope; red signals correspond to chloroplasts and green signals correspond to VIPP1 oligomers visualized through the expression of VIPP1 fused to green fluorescent protein.
